    K770i Unlock Inactive Sim

    I have flashed the mbn, fbn, tpa and relative vkp with jdflasher, everything went fine. Now all sims put in the phone come up as "inactive sim" but they will tell you what network the sim card is on. What is the problem here? The SIMs work in other phones.

    Would really appreciate help

    are you saying that jdflasher doesn't work for applying unlock patches?

    If you don't have backed up your GDFS you can still fix your phone imo:
